Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a vertical vacuum cleaner in which an electric rotating brush is installed in a floor suction device.

Prior Art Conventionally, the structure of this type of vertical vacuum cleaner was developed in U.S. Pat.
As shown in the drawings described in Publication No. 20958, the main body for accumulating dust is provided in close proximity to a floor suction device having a rotating brush and an electric motor for driving the brush, and a holder for supplying electric power to the electric motor. Wiring was done by connecting the plug at the end of the cord pulled out from inside the floor suction device to the outlet formed on the bottom of the unit.

In addition, the handle to operate this vertical vacuum cleaner is
It was formed at the tip of a pipe that was inserted into the rear of the main body and extended upward.

Problems to be Solved by the Invention Due to the above configuration, when the device is used in a narrow place such as under a desk, there is a problem in that each time the main body is moved, it hits the surrounding area and cannot be cleaned as desired.

Additionally, the plug was connected to the outlet at the bottom of the main unit, so if you lowered the height of the handle from the floor to clean under the bed, the plug would hit the floor, causing repeated damage. It also had the disadvantage of being damaged.

The present invention solves these conventional problems and provides a vertical vacuum cleaner that is much more convenient to use.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems is to provide a floor suction device having a front upper part of the main body containing an electric blower, a rotating brush, and an electric motor for driving the blower. Connect the cord with an extension tube and pull it out from the floor suction device to supply power to the motor. Connect the plug provided at the end of the cord to the outlet provided below the extension tube connection section on the front of the main unit. This is done by

Effect This effect prevents the main body from hitting the surrounding area even if the floor suction device is moved as much as possible by moving the main body far from the floor. By placing it on the side, this prevents the same part from hitting the floor, furniture, etc. during use and causing damage.

Example Examples thereof will be described below based on the accompanying drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a main body that incorporates an electric blower 2 and a cord winding device 3. A dust collection chamber is formed on the intake side of the electric blower 2, and a lid 4 is connected to the dust collection chamber by the action of a buckle 6. It can be opened and closed freely. An extension tube 6 is slidably held on the inner surface of a connecting tube 7 built into the upper part of the main body case 1, and is fixed to the main body case 1 at any extended position by a locking device 8.

Reference numeral 9 represents a handle formed to protrude from the end surface of the main body 1 on the side opposite to the side where the locking device 8 is disposed, and 1o represents a floor suction tool connected to the extension pipe 6. The floor suction tool 10 includes an electric motor 11 and a rotating brush 12 driven by the rotation of the electric motor 11. 1
Reference numeral 3 denotes an outlet provided at the front of the main body 1, that is, below the locking device 8 on the side of the floor suction device 10, and is electrically connected to the cord 14 wound around the cord winding device 3. 1
6 is a cord pulled out from the floor suction device 1o, which is wound into a coil shape so that it can be easily expanded and contracted.

When the plug 17 at the tip is connected to the outlet 13,
An electric circuit is formed so that electric power can be supplied to the electric motor 11 of the floor suction tool 10.

Next, the effect of the above configuration will be explained. As shown in FIG. 2, the general usage condition is to pull out the extension tube 6 from the main body 1 as far as it will go, fix it with the locking device 8, and then use the handle 9.
This is done by holding the handle 9 and moving the vacuum cleaner back and forth. At this time, since the cord 16 is wound into a coil, the winding pitch is extended along the extension tube 6, so that there is no problem in operation. Further, in this state, the main body 1 is separated from the surface to be cleaned by about 50 z, so even if the floor suction tool 10 is inserted into a narrow place such as under a desk, the main body 1 will not hit the surroundings and cannot be operated as desired.

In addition, when using it in a narrow place such as inside a car, the extension tube 6 is stored in the main body 1 as shown in Fig. 1, but in this case,
The outlet 13 and the plug 17 are located between the straight line A connecting the floor suction device 1o and the bottom of the main body 1 and the locking device 8, so that the outlet 13 and the plug 17 are not placed in a hard place during use.
7 does not occur and does not come into contact with the cleaning surface, so there is no chance of damaging the same part. In addition,
This prevention of damage to the plug 17 and outlet 13 is the same even when the aforementioned extension tube 6 is stretched.

In addition, although the above explanation deals with the case where the extension tube 6 is extendable, the effect is the same even with a vacuum cleaner that is used with an extension tube connected as shown in Fig. 3. It does not specify how to connect the pipe, but the point is that the cord that supplies power to the motor can be connected to the extension pipe on the front of the main body case or to the outlet provided under the floor suction device connection part. good.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, the present invention provides a vertical vacuum cleaner that includes a main body incorporating an electric blower, a floor suction device having a motor and a rotating brush that is rotated by the electric blower, and these connected by an extension pipe. In this case, the cord for supplying electric power to the electric motor exhibits the following effects by connecting it to the extension tube of the main body or the outlet provided below the floor suction device connection part.

10 In normal use, the main body does not interfere with the moving operation of the floor suction tool, and sufficient cleaning is possible even in narrow spaces, improving usability.

■0 Even under normal conditions or when using the main unit and the floor suction device close together, the plug of the cord that supplies power to the motor and the outlet formed in the main unit will not be damaged, resulting in increased durability and safety. will improve.
